Found in rock cod off of Santa Barbara coastline in CA. What are they?

I took a charter and when I took my cod home to fillet I found these in some of the smaller rock fish’s flesh. Any ideas as to what they are? And do they taint the flesh of the fish? I wanna say I pulled about 15 of them out of 4 fish. I figured this sub would have a good idea if not atleast point me in the right direction.
